Production and uses

The reaction of ethylene oxide with aqueous ammonia first produces ethanolamine:

C₂H₄O + NH₃ → H₂NCH₂CH₂OH

which reacts with a second and third equivalent of ethylene oxide to give DEA and triethanolamine:

C₂H₄O + H₂NCH₂CH₂OH → HN(CH₂CH₂OH)₂

C₂H₄O + HN(CH₂CH₂OH)₂ → N(CH₂CH₂OH)₃

About 300M kg are produced annually in this way. The ratio of the products can be controlled by changing the stoichiometry of the reactants. DEA is used as a surfactant and a corrosion inhibitor. It is used to remove hydrogen sulfide and carbon dioxide from natural gas.
In oil refineries, a DEA in water solution is commonly used to remove hydrogen sulfide from various process gases. It has an advantage over a similar amine ethanolamine in that a higher concentration may be used for the same corrosion potential. This allows refiners to scrub hydrogen sulfide at a lower circulating amine rate with less overall energy usage.
DEA is a versatile chemical intermediate, principal derivatives include ethyleneimine and ethylenediamine. Dehydration of DEA with sulfuric acid gives morpholine:

Amides derived from DEA and fatty acids, known as diethanolamides, are amphiphilic.

Commonly used ingredients that may contain DEA

DEA is used in the production of diethanolamides, which are common ingredients in cosmetics and shampoos added to confer a creamy texture and foaming action. Consequently, some cosmetics that include diethanolamides as ingredients may contain traces of DEA. Some of the most commonly used diethanolamides include:

·         Cocamide DEA

·         DEA-Cetyl Phosphate

·         DEA Oleth-3 Phosphate

·         Lauramide DEA

·         Myristamide DEA

·         Oleamide DEA

·         Triethanolamine
